Abstract:

Objective　To understand morphological classification and the incidence of neonatal auricular deformities，and obtain neonatal auricular measurement data.  Methods　With human body measurement instrument, we measured length, breadth and other items of newborns' Ear, and tookpictures of their both ears. In total we measured 321 newborns who were born in the Hospital of Dongguan Houjie within a week. According to the diagnostic criteria of auricular deformities, we determinde morphological classification, obtained the incidence of various types, differences between left and right, gender differences, and measurement data.　Results　There were eight morphological classifications in 321 newborns. They were Prominent ear, Cup ear, Lop ear , Stahl's ear, Constricted ear, Conchal crus, Helical rim deformity, and Mixed ear deformity. The incidence of Prominent ear was 3.74%, Cup ear 2.18%, Lop ear 5.61%, Stahl's ear 2.49%, Constricted ear 13.40%, Conchal crus 6.07%, Helical rim deformity 5.92%, Mixed ear deformity 4.05%. Compared with the left ear, the incidence of conchal crus of right ear was higher. The incidence of Helical rim deformity of female baby was higher than that of male baby.　Conclusion　The incidence of neonatal auricular deformities is high. There are differences of diagnostic classification of auricular deformities between home and abroad. We need to carry out multi-center cooperative research to determine the quantitative diagnosis of auricular deformities of Chinese newborns.
